A plication filed Octobt'r e, 1922. Serial no. 59mm.v

1 '0 all whom-it may concern: Be it known that I, Josnrii H. Porn, acitizen of the United States, residing at Hamilton, in the county ofEssex and State of Massachusetts, have invented -certain Improvements inLast Supports, of which thefollowing description, in connection with theaccompanying drawings, is a specification, like reference characters onthe drawings indicating like parts in the several figures.

The present invention relates to devices for supporting lasted shoes foroperations upon them, as the attachment of the heels, and is moreparticularly concerned with the protection of the lining or otherportion of the upper against being caught between the last and itssupport when'the lasted shoe is jacked or is put under pressure duringthe operation. V

()bjects of my invention are toprovide a simple, inexpensive andeflicient'protective device which will act substantially simultaneouslyabout the entire support. These objects I attain through the employmentof a continuous member surrounding the support and movable toward andfrom the jacked shoe thereon. Preferably, this member is expansible,being shown as in the form of a helical spring arranged for contact withthe interior of the shoe. In the illustrated embodiment of theinvention, the member upon which the last is supported includesrelatively movable sections, between which the encircling spring ismovable outwardly under their influence. This single workengagingmember, wholly without other movable supports than those which itsurrounds and free from pivoted connections, gives the desiredcontinuity of, action an contact with the lining about the interior ofthe shoe, thrusting said lining away, uniformly in all directions, fromthesuppoi't when the last is pressed into engagement with it. When thelast member of the support is arranged for oscillation to betterposition the work for theoperations upon it, the lining protector, isbest carried by the member, so that its relation to this element m andto the supported work is maintained constant.

One form which my invention may as sume appears in the accompanyingdrawing,

opening .Fig. 1 support or as a part of a heeling machine;

Fig. 2, being an end elevation of the jack showing, inside elevation, alastwith portions in section on the line2 2 of Fig. 1; I N Fig. 3, aplan view of the jack-top; and Fig. 4, a vertical section therethroughon the line H of Fig. 3.

The numeral 10 designates a jack .of a heeling machine, as of theLightning type, with its associated toe-rest 12 and the dieblock l-l,with which it cooperates. Carried at the top of the jack is a last-slide1t), lIlOUDtGCl'tO nioveytransversely in ways 18 so that the work may becorrectlypositioned beneath the die-block-openings. In the slideisformeda socket 20 adapted to receive a generally sphericalv head 22 upon alast-pin 24L 7 Furnishing the upper portion for this socket and beingsecured in place upon theslide by screws 26 is a plate 28, overhangingthe head 22 at an opening registering with the top of the socket. Thelast-pin 24: is designed to enter the vertical bore Z) in the cone 0 ofav last L, it giving, by virtue of its oscillationin the socket, alateral adjustment to permit the work to conformto the pressure appliedto it by the operating elements of the machine, as when the heel H whichis to be attachedto the lasted shoe S is pressed against the under sideof the die-block 14 preparatory to driving the heel-attaching nails, Acontactprojection 33, preferably cylindrical in form, depends from theunder side of the head 22, and, by its contact with the lowercylindrical portion of the socket, limits the movement of the head inthe socket, and

' The last-pin carries, upon a shoulder 30 ofthe head 22, alast-bed-plate 32, which supports the crown-portion of the cone of thelast, holding it againstniovenient longitudinally of the jack for theoperations upon the lasted shoe. This bed-plate preferably includes twosections, the lower 34 being fast upon the head 22, and the upper 86surrounding the pin which passes through an 38 in it, this upper sectionbeing free for limited movement along the pin. It is held againstseparation from the fixed plate and the extent of its movementdeterjack, with its lining-protector,

mined by screws 40 passing through openings in the plate-section 34 andbeing threaded into the section 36. Heads 42 of these screws lie withincounterbores of the plateopenings, contacting with the inner extremitiesthereof at the limit of upward movement. The edges of the sections 34and 36 adjacent to each other are inclined at 44, diverging outwardly togive a generally V-shaped depression. In this depression is located acontinuous, expansible member, furnished by a helical spring 46, whichis always under some tension, this drawing the spring toward the bottomof the groove and holding the bed-platesections normally separated fromeach other. The diameter of the convolutions of the spring is such thatin this normal position, its outer side preferably projects somewhatbeyond the peripheries of the plates, so that when a shoe is jacked,with the bed-platesections, as well as the last-pin, within it thesecurved surfaces tend to deflect the upper, with its lining, outwardly,and prevent their entrance between the bed-plate and the crown of thelast.

In the operation of the machine, when pressure is applied to the lastedshoe, the movable bed-plate-section 36 is depressed, expanding thespring 46 and causing this to emerge from its depression, as bestappears in Fig. 2 of the drawing. This engages the lining of the upperabout the entire support, thrusting it away, not only from the junctureof the last and bed-plate, but also from the opposing surfaces of saidbed-plate and the slide, placing it beyond danger of being caughtthereby and mutilated. hen the pressure is removed, the spring 46contracts to separate the bed platesections, and is thus drawn into itsdepression, the parts resuming their normal relation. Whatever positionof self-adjustment the last-pin assumes in the operation of the machine,the bedplate and lining-protector move with it, so that the relation ofthe lining-engaging periphery of the spring 42 to the interior of thelasted shoe remains unaltered.

Having described my invention, what I claim as new and desire to secureby Letters Patent of the United States is:

1. The combination with a last-support, of a continuous lining-protectorsurrounding the support and movable toward and from a lasted shoe.

2. The combination with a last-support, of an expansible membersuro-unding the support and arranged for contact with the interior of alasted shoe.

3. The combination with a last-support,

of a work-engaging spring surroui'iding the support.

4. The combination with a last-support, of a helical shoe protectorcarried by the support and movable toward a lasted shoe.

5. The combination with a last-support, of a spring surrounding thesupport, and means for expanding the spring.

6. In a last-support, a last-supporting member including relativelymovable sections, and a shoeengaging spring movable by the sections andindependently of said sections.

7, The combination with opposite lastsupporting plates having a spacebetween their edges, of a lining-protecting member encircling the space.

8. The combination with opposite lastsupporting plates having oppositelyinclined edges relatively movable toward and from each other, of ahelical spring contacting with said edges.

9. In a jack, alast-pin, a last-bedplatesection mounted in fixedrelation to the pin, a bed-plate-section movable upon the fixed section,and a lining protecting member encircling the plat-es and arranged toact upon the movable section.

10. In a jack, a last-pin, a last-bedplatesection mounted in fixedrelation to the pin, a bed-plate-section movable upon the fixed section,a lining-protecting member encircling the plates and arranged to actupon the movable section, said plate-sections having converging inclinededges, and a helical spring situated between said edges.

11. In a last-support, a last-pin arranged for universal movement, and alining-pro tector carried by the pin and sharing in its universalmovement.

12. In a last-support, a last-slide, a lastpin movable thereon, and alining-protector carried by the pin, all these elements being arrangedto enter a lasted shoe.

13. The combination with a jack-top having a socket, a ball movable inthe socket, a last-pin projecting from the ball, a lastbed-plate carriedby the pin, and a member mounted for movement upon the bed-plate andarranged to engage a lasted shoe.

14. The combination with a jack-top having a socket, a ball movable inthe socket, a last-pin projecting from the ball, a last bed-platecarried by the pin and having relatively movable sections, and aworkengaging spring interposed between the sections.

In testimony whereof I have name to this specification.
